Basic Skinstinct: Part 2!
Not only did she expose arms and major thigh in her red one-shoulder Roberto Cavalli gown, but the 55-year-old (yes, 55!!) also put the girls on display by showing some serious side and underboob!
The sexy momma paired the outfit with Jimmy Choo shoes and a gold clutch.
While we wish Sharon did more with her hair, the rest of her looks incredible - even when she was out partying on Cavalli's yacht into the wee hours!
Hmm, guess we could see why the two have remained good friends over the years if she looks this red hot in his clothes!
